The Vortex 5C Metric Lathe Collet, Hex 18 mm, is a soft emergency collet designed for use in a 5C lathe chuck. It’s purpose-built for shops that need a custom-fit bore, depth, taper, or shape to suit a specific component, without buying multiple fixed-size collets. Pins are fitted to keep the collet open during boring, enabling precise modification while the part remains secured in the chuck.

• 13–15 micron runout for precise results: Delivers tight concentricity to help maintain accuracy on small, delicate parts and reduce finish and tolerance issues during boring operations.
• Bore-to-fit customization with open-pin guidance: Soft collet material can be bored to your exact size, depth, taper, or shape, while pins hold the opening open in the 5C lathe chuck for safe, controlled setup and modification.
• Re-boreable for long-term value: Designed to be re-bored many times to hold larger parts later, maximizing reuse and reducing the need for new collets as your work evolves.

This collet provides a practical, flexible solution for custom component work, enabling precise internal diameters and tailored fits without sacrificing workflow efficiency. By combining adjustable bore capability with reliable 5C chuck compatibility, it supports consistent results, faster setup times, and better overall part quality—from prototypes to small-batch production.
